Clemmings played in six games with Washington and had two starts last year under coach Jon Grudens brother Jay before going on injured reserve with an ankle injury. He started 30 games in 2015-16 for the Minnesota Vikings after being a fourth-round pick out of Pittsburgh.

Signed by Denver as an undrafted free agent in 2016, Murray, 25, never caught on in Denver and was signed to practice squads in Tampa Bay and New Orleans before landing on the practice squad of the Bengals. He was added to the Bengals 53-man roster last Dec. 20 but saw no game action.

Sharpe was a fourth-round draft pick out of Florida who played in five games with two starts. He came in lighter this season and was a competitor to be a backup tackle. Silberman, who can also play guard, drew praise from the Raiders coaching staff last year and this year at camp.

Defensive tackle Mario Edwards Jr., a former second-round draft pick by the Raiders, was claimed by the New York Giants on waivers after being released. Edwards was pushed off the roster in large part due to strong training camps from draft picks P.J. Hall (second round) and Maurice Hurst (fifth round).
